98. It's McCartney

Lennon and McCartney have Irish heritage. Not sure about Harrison, but its likely. Starr doesn't have Irish heritage as far as I know.

If you go around England, there are plenty of Irish bars here. Temple Bar in Norwich, etc, because Irish Catholics came to England and Wales during the troubles for better job opportunities and one such city that has a concentration on Irish heritage people is none other than Liverpool. I recently discovered that I have A LOT of relatives in Liverpool.
